xmltv/grab/sd_json tv_grab_sd_json,1.16,1.17

Update of /cvsroot/xmltv/xmltv/grab/sd_json
In directory sfp-cvs-1.v30.ch3.sourceforge.com:/tmp/cvs-serv22019

Modified Files:
	tv_grab_sd_json 
Log Message:
tv_grab_sd_json: Allow search by transmitter for more than GBR.
    
It turns out I was mistaken that only GBR is supported for transmitter
search. I now parse the available countries from the response to the
/available API.
